Abstract

L'invention divulgue un procédé de dégradation du 1,4-dioxane dans les eaux usées produites pendant la fabrication de sulfates d'éther d'alkyle. Le procédé comprend les étapes consistant (a) à mélanger de 100 à 10 000 ppm, de préférence de 1 000 à 4 000 ppm d'ozone avec les eaux usées ; (b) à introduire H2O2 dans les eaux usées à une quantité de 0,01 à 10, de préférence de 0,1 à 0,5 équivalents molaires de H2O2en ozone, et (c) à mélanger l'ozone, H2O2, et des eaux usées pour générer des radicaux hydroxyle réactifs avec le 1,4-dioxane, sans ajout d'un catalyseur métallique. Les radicaux hydroxyle réagissent avec le 1,4-dioxane et le dégradent en dioxyde de carbone, eau et/ou carbonate. Le procédé est efficace pour réduire une concentration de 1,4-dioxane dans les eaux usées d'une plage d'environ 10 ppm à environ 1000 ppm de dioxane jusqu'à moins de 5 ppb de 1,4-dioxane après traitement. Le procédé est également efficace pour éliminer des types d'hydrocarbures qui peuvent être présents dans les eaux usées.
